analytical-imaging
Analytical imaging encompasses a suite of advanced microscopy, spectroscopy, and imaging techniques used to visualize and quantify the chemical, structural, and functional properties of plant tissues at high resolution. By enabling non-destructive, spatially resolved analysis of everything from cell wall composition to pigment distribution, these methods allow researchers to link molecular-level measurements directly to plant anatomy and physiology. This integration of imaging and chemical analysis accelerates discoveries in areas such as stress response, nutrient transport, and developmental biology.

Scientists have created a powerful imaging technique that can photograph the chemical activity happening inside plant tissues — revealing where specific molecules are located without needing to tag or alter the plant. This review summarizes how the technology works and what it has already uncovered about plant metabolism, medicinal compounds, and how plants respond to disease and stress.
Three major ionization platforms — MALDI, DESI, and SIMS — each offer distinct trade-offs in spatial resolution and sensitivity for mapping plant chemistry, giving researchers a toolkit for different research questions.
MSI has enabled direct spatial mapping of bioactive compounds in medicinal plants, pinpointing exactly which tissues produce and store pharmacologically relevant molecules.
The technique has revealed molecular-level mechanisms of plant-microbe interactions and stress responses, providing insights into metabolic regulatory networks that were previously inaccessible without destructive sampling.
